Uppercased execution type not recognized and command fails

[Felipe Kraemer]

If the following is executed:

atl fecru 4.4.1 START

START is not getting converted to lowercase and the command fails as a consequence. The following is written:

Invalid execution type. Valid options are 'install', 'start', 'stop' and 'restart'. Script will terminate.

[Felipe Kraemer]

There was a problem when converting the argument received by the script into lowercase. Line #19 was changed from:

START="$(tr [A-Z] [a-z] <<< "$START")"

to the following:

EXECUTION="$(tr [A-Z] [a-z] <<< "$EXECUTION")"

Now the script works even if the argument is uppercased.

Commit aa777f5 fixed this bug.
